PARTITION-WALL.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed September 26, 1907. Serial No. 394,767.

To all whom it may concern:

Be it known that I, WILLIAM J. PERKINS, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, tain new and useful Improvement in Partition-Walls, of which the following is a My invention relates to a new and useful improvement in a partition wall, and has for its object to simplify said construction and increase the eflioiency of partitions built in accordance with my invention.

With these ends in view, th1s lnvention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated byjthe claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same I will gescribe its construction in detail, referring Y forming a part of this specification in which a Figure 1- is a perspective view of a portion of a partition constructed in accordance with my invention, a part of the plaster boards being removed, and a portion of the white coating being broken away to clearly. illustrate the details thereof. Fig. 2- a vertical section showing the filling between the plaster boards.

Fig. 4- a similar view of one of the clips, the upright channel iron to'which it is' attached being'in dotted lines.

In carrying out my invention as here embodied, A represents the uprights which are preferably made ofchannel" iron the same being set at a proper distance apart and secured to the floor, so as to form studs forthe support of the partition.

B are strips made preferably of channel iron, secured to the upper ends of the uprights A, and the latter are in turn secured to the ceiling, by means of angle irons w, as a further means of supporting the completed partition. A series of the clips 0 are secured upon the bottom of the uprights, as hereinafter explained. The first row of plaster boards D is then set in place, and the rows of clips C are secured to the uprights so as to bring the flanges thereof over the edges of the plaster boards, thus holding them in place,

have invented a cercement has previously forcing this bag against the ceiling and flattening it out its contents will be forced into A letter to the accompanying drawing,

in the usual manner Fig. 3 a detailed perspective view of one of the plaster boards,

when the filling which is composed of the following ingredients hereafter named in liquid form is poured in the space between the plaster boards, which adheres to the inner surface of said boards and will form a solid wall. This is repeated until all but the top row of plaster boards are secured in place and filled. After this has been accomplished the top row of the plaster boards is then set inplace, and the clip E the ends of which project over the edges of this top row of boards, will hold the latter in place; and for the purpose of inserting the filling between these top rows of boards, small openings or notches F are cut in a certain part of these top rows of boards, through which the nozzle G is inserted, said nozzle having attached thereto a filling bag H into which a quantity of the been placed. When the space between the boards, thus completing the wall, after which a plug may be fitted into the small 0 enings or notches. The next step is the app ication of the white coat indicated at I, and when this is applied the partition will be finished and ready for painting or papering.

Each of the clips C consists of a sheet of metal, so cut and bent as to form the flanges or teeth a adapted to lap over the edges of the plaster boards as clearly shown in Fig. 1, and hold them against outward movement.

; This clip has also formed therewith the lug b which serves as a spacer, holding the opposite plaster boards at a proper distance l art. In order that the clips may be readily secured to the uprights, a tongue d is partially cut therefrom and bent rearward around which the wiree is passed, said wire being twisted tightly around the uprights thus holding the clips in place. This clip not only holds the boards in place sidewise but also supports said boards on the studs so as to relieve the lower boards from undue strain.

The plaster boards may be made of any length or width desired, but are preferably made from the following ingredients in the proportions named: one quart of plaster paris, two quarts of fine coal ashes, one

pintof Portland cement, and one pint of bar sand, and fiber either animal or vegetable to give strength, to which is added water, the whole being mechanically mixed to the consistency of thin mortar.

The boards are formed into suitable molds to give them the proper size and shape, preferably four feet long and sixteen inches wide, and five-eighths of an inch thick.

The filling which is used to bind the boards together when making up the partition, preferably consists of, one quart of plaster paris, three quarts of ashes, one pint of Portland cement, and one pint of bar sand, the same being mixed with water until enough to flow freely.

The plaster boards should break joints at the studs, so that no two joints will come opposite to one another, and I prefer that the studs shall be set sixteen inches apart.

The partition made in accordance with my improvement will not only be rigid, but will be sound proof as well as fire proof and may be made of any thickness by simply placing the plaster boards at a proper distance apart, and such partitions can be constructed at very much less cost than by the old method.

I Having thus fully described my invention, what I claim as new and useful is 1. A partition Wall embodying uprights, and plaster boards with means for securing said boards to said uprights, consisting of clips having a horizontal part formed with a cut-away portion to receive said uprights and with an upwardly extending tongue, a wire engaging about said uprights and engaging said tongue to secure the clips to the uprights, and a series of oppositely disposed teeth along each side of said horizontal part to engage the plaster boards.

2. In a partition wall, uprights and plaster boards with means to secure said boards to said uprights consisting of clips having a cutout part to receive said uprights, a tongue and a spacer carried by each clip and extending on opposite sides thereof, means engaging the upright and tongue to secure the clips to the uprights, and teeth 011 the clips to engage the boards.

3. In a partition wall, uprights and plaster boards, and clips to secure the boards to the uprights consisting of a horizontal part having a cut-out part to receive said uprights and a tongue which extends outward therefrom, means to secure the tongue to the upright, and a series of oppositely I arranged teeth on each side of said horizontal part.

I11 testimony whereof, I have hereunto affixed my signature in the presence of two subscribing witnesses.
